FOLDABLE SUPPORTING STAND FOR OPTICAL PROJECTING MACHINES Application filed November 7,1925. Serial 1 To.6'7,"558.v

This invention relates to supporting ings as at 12 of the legs so that they are stands for cameras and optical projecting held out of the way. The lower ends of machines, the object of the invention being the side bars 4t are provided with suitable to provide a simple, comparatively inexpen brackets 18, to which'at each end ofthe-stand s'ive, light weight, rigid, portable stand a pair of legs 14: are pivotally connected, which can be readily folded into a small these legs being so formed and connected to spa'ceandquickly adjusted into position for the brackets 13 that they are foldable up; supporting a camera or-other instrument.

Having thus explained the nature of my said invention and described a way'of constructingand using the same, although without attempting to set forth all of the forms in which it may be made, or all of the modes of its use, I claim:

1. A folding supporting stand for instruments comprising a top and bottom and a pair of side bars hinge connected to said top and bottom adjacent to the ends thereof, said top and bottom each being hinge connected intermediate its length to fold inward toward each other and toward the center of the stand and wholly within the side bars, and foldable legs for supporting the stand and foldable upwardly against the edges of said side bars.

2. A folding supporting stand for instruments comprising a top and bottom and a pair of side bars hinge connected to saidtop and bottom adjacent to the ends thereof, said top and bottom each being hinge connected intermediate its length to fold inward toward each other and toward the centerof the stand and wholly within the side bars, and foldable legs for supporting the stand and foldable upwardly against the edges of said side bars and having a length substantially coinciding with the length of the side bars. l 1

3. A folding supporting stand comprising a supporting'member, a shelf therebelow, a pair of side bars hinge connected to said supporting member and shelf adjacent-to the ends thereof, said supporting member and shelf each having a hinge connection intermediate itslength to fold inward toward each other and toward the center of the stand and wholly within the sidebars, and

supporting legs shiftably connected to said side bars.

4. A folding supporting stand comprising a supporting member,a shelf therebelow, a pair of sidebars hinge connected to said supporting member and shelf adjacent to the ends thereof, said supporting member and shelf each having a hinge connection intermediate its length to fold inward toward each other and toward the center of the stand and wholly within the side bars, supporting legs shiftably connected to said side bars, and means for maintaining the supporting member in its supporting position.

5. A folding supporting stand comprising a supporting member, a shelf therebelow, a

pair of side bars hinge connected to said supporting member and shelfadjacent to the ends thereof, sald supporting member and shelf each having a hinge connection interflmediate its length to fold inward toward each other and toward the center of the stand and wholly within the side bars, supporting member and shelf adjacent to theends thereof, said supporting member and shelf each having a hinge connection inter;- mediate its length to fold inwardtoward each other and toward the center of the stand and wholly withinthe side bars, supporting legs shiftably'connected to said side bars, and means for maintaining the shelf in its supporting position.

7. A folding supporting stand comprising a supporting member, a shelf therebelow, a pair of side bars hinge connected to said supporting member and shelf adjacent to the outer sides thereof, said supporting member and shelf each having a hinge connection intermediate its length to fold inward toward each other, supporting legs shiftably connected to said sidebars, means for maintaining the shelf in its supporting positionand comprising brace bars connected with the legs. j
